Re: [cdt-debug-dev] How to input a string as arg of MI command?

["Felix Yuan" <bigbrain_cn@xxxxxxx>]

Thanks alot.

But the approach to wrap the code in a runnable does not work.
The same error occurred when PlatformUI.getWorkbench(); was called.
Unhandled exception caught in event loop.
Reason:
org/eclipse/ui/PlatformUI

btw, I did not find the method getDisplay() in IWorkbench.

I know Mikhail's approach is much better. But in my case, the parameter will
change frequently. If it is set in the "Debugger" page of the launch
configuration dialog, users have to launch a new debugger session and modify
the configuration when they want to change the parameter. That's rather
complicated.
So, I need a simple and direct way to send parameters to one debugger
session.
